摘要
利用量子操作的无错分辨来考虑量子操作的精确分辨,得到了量子操作精确分辨的充要条件;其次,将量子态的集合分辨推广到量子操作的集合分辨,同时得到了两个充要条件;最后考虑了量子操作无错分辨的失败概率的下界。
Authors consider the perfect discrimination problem by applying the method of unambiguous discrimination quantum states to quantum operation,and get a necessary and sufficient condition for quantum operation;second authors extend set discrimination of quantum states to set discrimination of quantum operation,at the same time,obtain two necessary and sufficient conditions for quantum operation;at last, authors consider the lower bounds of the quantum operation.
